[0002] Casting is one of the basic processes of modern mechanical manufacturing industry and is a commonly used processing method in metal part processing. The specific process is to first inject molten metal or non-metal material into a pre-designed mold, and after it cools and solidifies, a formed casting with specific shape, size and performance is formed. In order to facilitate the removal of the casting, semi-molds that can be separated and combined are usually used. When the existing casting box is in use, the solidified casting is not easy to separate from the cavities of the two semi-molds, and it is necessary to manually knock the casting, which is easy to cause damage to the surface of the casting. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is that when the existing casting box is in use, the solidified casting is not easy to separate from the cavities of the two semi-molds, and it is necessary to manually knock the casting, which is easy to cause damage to the surface of the casting.

[0017] The utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0018] As Figures 1 to 4 shown, two mold bodies 10 of the casting box of the utility model are relatively slidably arranged on a bracket 11. A vibration groove 21 is opened at the bottom of the mold body 10, and a plurality of vibration grooves 21 are arranged at intervals along the sliding direction of the mold body 10; an electric push rod 22 is arranged on the bracket 11, the output end of the electric push rod 22 is connected with a vertical cylinder 23, a vibrating rod 24 is slidably connected in the vertical cylinder 23, and the upper end of the vibrating rod 24 slides along the vibration groove 21 to knock and vibrate the mold body 10.

[0019] After the casting in the cavities of the two mold bodies 10 solidifies and forms, the output end of the electric push rod 22 drives the vertical cylinder 23 to move, so that the upper end of the vibrating rod 24 slides along the vibration groove 21 to knock and vibrate the mold body 10, so as to loosen the cavity of the mold body 10 and the casting, facilitate the separation of the casting from the cavities of the two mold bodies 10, and there is no need to manually knock the surface of the casting, avoiding damage to the surface of the casting.

[0020] Preferably, referring to Figure 3, the vibrating chute 21 includes a vertical section 25, a horizontal section 26, and an inclined section 27 arranged in sequence along the extending direction of the output end of the electric push rod 22. The upper end of the vertical section 25 is connected to one end of the horizontal section 26, the other end of the horizontal section 26 is connected to the upper end of the inclined section 27, and the inclined section 27 is inclined from top to bottom along the extending direction of the output end of the electric push rod 22.

[0021] The output end of the electric push rod 22 drives the vertical cylinder 23 to move, so that the upper end of the vibrating rod 24 slides along the vibrating chute 21. The upper end of the vibrating rod 24 slides from the bottom of the mold body 10 to the horizontal section 26 to knock and vibrate the mold body 10. The upper end of the vibrating rod 24 slides along the inclined section 27 to the bottom of the mold body 10 and then performs the next knocking vibration, so as to cycle and knock and vibrate multiple times.

[0022] Preferably, referring to Figure 3 , 4 , the lower end of the vibrating rod 24 is rotatably connected to a push rod 29 through a rotating shaft 28. The push rod 29 is slidably installed in the vertical cylinder 23 through a compression spring 30. The rotating shaft 28 is arranged on one side of the lower end of the vibrating rod 24 close to the inclined section 27. A torsion spring 31 is sleeved on the rotating shaft 28. One end of the torsion spring 31 is fixed to the vibrating rod 24, and the other end is fixed to the push rod 29, so that the lower end surface of the vibrating rod 24 can contact the upper end surface of the push rod 29.

[0023] The output end of the electric push rod 22 extends and drives the vertical cylinder 23 to move correspondingly. Under the action of the torsion spring 31, the lower end surface of the vibrating rod 24 remains in contact with the upper end surface of the push rod 29, thereby driving the upper end of the vibrating rod 24 to slide along the vibrating chute 21 to knock and vibrate the mold body 10; when the output end of the electric push rod 22 retracts and drives the vertical cylinder 23 to move correspondingly, the upper end of the vibrating rod 24 moves reversely along the bottom of the mold body 10 and the vibrating chute 21, so that the vibrating rod 24 and the push rod 29 rotate relatively until the output end of the electric push rod 22 retracts to the initial state, thus facilitating cyclic use.

[0024] Among them, the vibrating rod 24 is not directly slidably connected to the vertical cylinder 23, but can reciprocate together with the push rod 29 as a whole in the vertical direction where the vertical cylinder 23 is located. Of course, preferably, the vibrating rod 24 can also rotate relative to the push rod 29.

[0025] Among them, the length of the vibrating rod 24 is greater than the length of the vertical section 25 so that the vibrating rod 24 can rotate relative to the push rod 29.

[0026] Among them, the cross sections of the push rod 29 and the inner hole of the vertical cylinder 23 are square and match each other.

[0027] Preferably, a handle 12 is provided on the mold body 10.

[0028] Among them, for the vibrating groove 21 at the farthest end from the electric push rod 22, the length of the horizontal section 26 thereof is greater than the lengths of the horizontal sections 26 of other vibrating grooves 21, so that after the mold body 10 is vibrated by knocking, the two mold bodies 10 are reversely moved a certain distance to be separated from each other through the handle 12, and then the demolding process of the casting is carried out. During this period, the output end of the electric push rod 22 is stationary, and the vibrating rod 24 and the ejector rod 29 will not rotate relative to each other or move up and down.

[0029] Preferably, referring to Figure 1 , locking ears 13 are provided on the mold body 10, and the two locking ears 13 are connected by bolts to fix the two mold bodies 10.

[0030] Of course, the two mold bodies 10 can also be fixed by other means, such as a snap structure or a frame and a locking bolt structure.

[0031] Among them, locking ears 13 are provided on both the front and rear sides of the two mold bodies 10.

[0032] Preferably, a rounded corner 32 is provided at the upper end of the vibrating rod 24 so that the upper end of the vibrating rod 24 can slide smoothly along the vibrating groove 21.

[0033] Preferably, a sliding rod 33 is provided at the bottom of the mold body 10, and a sliding rail 34 is provided on the bracket 11, and the sliding rod 33 slides along the sliding rail 34.

[0034] Among them, two groups of sliding rods 33 and sliding rails 34 are symmetrically arranged along the center line of the mold body 10.

[0035] Among them, the cross sections of the sliding rod 33 and the sliding rail 34 can be dovetail-shaped or T-shaped that cooperate with each other.

[0036] The working principle of the present utility model is as follows:

[0037] After the casting in the cavities of the two mold bodies 10 solidifies and forms, the electric push rod 22 is started, and the output end of the electric push rod 22 is controlled to extend, driving the vertical cylinder 23 to move correspondingly. Under the action of the torsion spring 31, the lower end surface of the vibrating rod 24 remains in contact with the upper end surface of the ejector rod 29, thereby driving the upper end of the vibrating rod 24 to slide along the vibrating groove 21. Specifically, the upper end of the vibrating rod 24 slides from the bottom of the mold body 10 to the horizontal section 26, and under the action of the compression spring 30, the mold body 10 is vibrated by knocking. The upper end of the vibrating rod 24 then slides along the inclined section 27 to the bottom of the mold body 10, and then the next knocking vibration is carried out. Such cyclic knocking vibrations are carried out multiple times, so that looseness is generated between the cavity of the mold body 10 and the casting, facilitating the separation of the casting from the cavities of the two mold bodies 10, without manually knocking the surface of the casting, avoiding damage to the surface of the casting;

[0038] After the mold body 10 is knocked and vibrated, due to the relatively long length of the horizontal section 26 of the vibration groove 21 at the farthest end from the electric push rod 22, the two mold bodies 10 can be moved in opposite directions by a certain distance through the handle 12 until they are separated from each other, and then the demolding process of the casting can be carried out. During this period, the output end of the electric push rod 22 remains stationary, and the vibration rod 24 and the ejector rod 29 will not rotate relative to each other or move up and down.

[0039] Control the output end of the electric push rod 22 to retract, drive the vertical cylinder 23 to move in the corresponding opposite direction, and the upper end of the vibration rod 24 moves in the opposite direction along the bottom of the mold body 10 and the vibration groove 21, so that the vibration rod 24 and the ejector rod 29 rotate relative to each other until the output end of the electric push rod 22 retracts to the initial state. At the same time, the upper end of the vibration rod 24 is located in the original vibration groove 21; then the two mold bodies 10 are combined and fixed through the locking ears 13 and bolts, so as to facilitate recycling.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
